Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed November 22, 1906. Serial No. 344,538.

To all whom it may concern:

Be it known that I, CASPER SCHAEFER, a citizen of the United States, residing at Cambridge City, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Combination I-Ieate rs and Radiators; and I do declare the following to be a fulhclear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to apparatus of the class that may be used either as a gas heater or as a stove pipe radiator, the invention having reference particularly to heat radiators that are adapted for heating dwellings.

Objects of the invention are to provide improved highly eflicient radiators at moderate expense and which may be durable and economical in use, another object being to provide means whereby radiators of the above-mentioned character may be readily cleaned and kept free from soot conveniently in order to obtain the best results with the least amount of heat, a still further object being to provide a gas heater which may be adapted to be readily connected to a stove pipe to be used as a radiator.

With the above-mentioned and minor objects in view, the invention consists in an improved radiator provided with a detachable gas burner and adapted to be connectedto a stove pipe, the radiator having adjustable and movable connected baffle plates therein serving as scrapers, and having also a movable scraper for cleaning the interior of the shell of the radiator; and the invention consists further in the novel parts and the combinations and arrangements of parts as hereinafter particularly described and pointed out in the appended claims.

Referring to the drawings, Figure 1 is a side elevation of the heating apparatus provided with a gas burner and connected to a stove pipe, the shell being partially broken away to expose internal parts; Fig. 2, a top plan of the radiator disconnected from the stove pipe; Fig. 3, a vertical central sectional view with the supporting legs and gas burner omitted; Fig. 4, a horizontal sectional view on the line A A in Fig. 1; Fig. 5, a side elevation showing the baflle plates and their connector which serves as a heat deflector and the handles for the operation and adjustment thereof; Fig. 6, a top plan of one of the two baffle plates employed as seen looking down at the line B B in Fig. 3; Fig. 7, a perspective view of the shell scraper; and, Fig. 8, a fragmentary perspective view of a portion of the shell scraper.

Similar reference characters in the various figures of the drawings designate corresponding elements or features of construction.

In a practical embodiment of the invention a designates a base plate, and a a top plate of the radiator which have circular openings b and b respectively, arranged in circles, the plates being circular in plan and connected to opposite ends of a tubular shell 0. A suitable number of heating tubes (I are connected to the said plates at the openings 1) and b therein for the passage of air to be heated. The base plate a is provided with a suitable number of supporting legs e and has a central annular flange f extending about an inlet opening and adapted to be connected to a stove pipe. The top plate a is provided with an annular flangef to which a stove pipe 9 may be connected for conducting smoke or fumes from the interior of the radiator. The collars f and f have less diameter than the circle of heating tubes. A suitable burner holder h is detachably connected to the flange f by means of bolts h, and a gas burner 't having an inlet pipe i is supported by the holder so as to be central below the base plate a opposite the inlet opening'therein. extend from the plate a to the plate a and secure them to the shell and the tubes.

Two baffle plates is and k each have a suitable number of circular openings Z to receive the heating tubes d, and the bafl le plates may slide over the tubes, the plates preferably having scalloped edges Z. A tube m extends between the two baffle plates is and It and is secured thereto holding the baffle plates at a suitable predetermined distance apart so that all may be moved together. The baffie plates have openings n and 11/ therein through which extend handle rods 0 and 0 which are secured to the bathe plates by means of fasteners p which may be formed as U-bolts or staples. The handle rods are provided with stop pins q inserted in pin holes 7 so that the baffle plates may be supported adjustably by permitting the pins to rest upon the top plate a.

In order to scrape the inner side of the shell 0 to remove soot therefrom, an annular scraper s is arranged within the shell and extends about the group of heating tubes d and is provided with handle rods t and t of sufficient length to extend entirely through the top plate a when the scraper is down, at or near the base plate a, so that the scraper may be moved throughout the whole length of the casing. The scraper and the handle rods are preferably made of two pieces of wire, each piece being bent to form a half part of the scraper and attached to the opposite handle rod by being twisted about it as at it, although obviously the scraper may be otherwise constructed.

In practical use the radiator should be placed upon a floor over a stove pipe hole therein, and the stove pipe extended through the floor and connected to the flange f by swinging the holder h out of the way and shifting the position of the burner i so as to clear the stove pipe, or in case the heating-stove may not be in Suitable rods j use, the stove pipe may be readily disconnected from the flange f and then the gas burner may be quickly placed in proper position as indicated in Fig. 1, so that the room may be heated conveniently by means of the gas burner.

In case of accumulations of soot on the inner side of the shell 0 and on the exterior oi; the tubes (1, the surfaces may be readily scraped by means of the scraper s and the baflle plates It and k serving as scrapers as above indicated, which will be found of great advantage in obtaining the highest degree oi radiation of the heat, it being understood that the hot gases and the smoke, it any, will be deflected by the plate It so as to pass upwardly around the plate and will be deflected by the connector m towards the heating tubes (1 between the plates k and k, and then deflected by the plate 70 around the edge thereof, the gases then passing out of the radiator through the pipe 9. The soot will drop down onto the plate a, but with a strong drait much of it will pass out through the pipe 9 and the chimney flue, but in case of an accumulation on the base plate a, it may remain without serious detriment, and in such case it may be desirable to readjust the plates 70 and It so as to elevate them somewhat, and while the plate a may be entirely free from soot, the batlie plates niay be lowered so as to deflect the heat to the shell and tubes near the bottom of the radiator.

Ordinarily there will be no occasion for disconnecting the stove pipe from the radiator for removing the soot during a whole winter season, and not at all it the scraping devices are frequently used so that unusual deposits will be avoided, it being understood that the scrapers will break up or pulverize the soot, so that it may readily pass out with strong draft.

Having thus described the invention, what is claimed as new is 1. A radiator comprising a shell, a circular group of heating tubes, a pair of end plates connected to the shell and the tubes, a pair of bailleplates movable on the tubes, a tubular connector within the circular group of tubes at tached to the baifleplates and movable therewith, and a pair 01: handle-rods connected to one of the battle-plates.

2. A radiator comprising a shell, heating tubes, a pair of end plates connected to the shell and the tubes, and an adjustable deflector comprising a pair of ballleplates and a tubular connector guided by the tubes, the connector being attached to the bathe-plates, and the baille-plates having openings to receive the tubes.

A radiator comprising a shell, heating tubes, end plates connected to the shell and the tubes, :1 pair of battleplates movable on the tubes and having a tubular connector attached thereto serving to deflect currents towards the tubes, and means for moving and adjusting the baflleplates and the deflecting connector with respect to the end plates.

4. A radiator comprising a shell, a group of heating tubes, end-plates connected to the shell and the tubes, a

pair or ballleplates movable on the tubes, a tubular con-' nector attached to the bathe-plates spacing them apart and movable therewith, handle-rods connected to one of the halite-plates, a scraper adjacent to the shell and movable about the group of tubes and past the bailie-platcs and connector, and a handle-rod connected to the scraper.

5. A combination heater and radiator comprising a baseplate with an inlet opening therein, a shell and a circular group of heating-tubes connected to the base-plate, an aperture top-plate connected to the shell and the tubes, supporting legs attached to the base-plate, a burner-holder connected adjustably to the base-plate, a gas burner mounted removably on the burner-holder, a pair of baflleplates movable on the tubes, a tubular connector attached to the baIlle-plates and movable therewith, and a pair of handle-rods connected to one of the ballleplates.

(3. The combination with a radiator having a shell and a circular group of heating tubes, and end plates connected with the shell and the tubes, of a pair of ballle-plates spaced apart on the tubes, a tubular connector within the circular group of tubes and attached to the ballleplates, and a pair of handle-rods attached to one of the pair of bathe-plates and provided with stops to cooperate with one of the end-plates to gage and hold the battle-plates rela tively to the end-plates.

In testimony whereof, I aifix my signature in presence of two witnesses.
